UNITED STATES ARTHUR LANGERFELD,

OF NEW YORK, N. Y.

BABY-FOOD WARMER.

SPECIFICATION forming part of Letters Application filed March ll, 1895.

To @ZZ 71:71pm, 711 may concern,.-

Be it known that I, ARTHUR LANGEREELD, of the city of New York, in the county and State of N ew York, have invented a new and useful Baby-Food Varmer, of which the following is a specification.

My invention relates to improvements in apparatus for Warming milk in bottles for baby-food, especially sterilized milk, to the natural temperature of mothers milk, and is also useful for warming other things to certain temperatures; and the objects of my invention are, rst, to provide meansfor conducting the heat directly to the bottle or article to be warmed instead of conducting it indirectly by means of a bath, as was done heretofore. By this object I accomplish a saving of time and fuel. Second, to provide means for preventinga waste or loss of heat; third, to provide means for warming the bottle evenly; fourth, to provide means for attaining a certain temperature alternately, and, fth, to provide means for warming the bottle gradually. I attain these objects by the apparatus illustrated in the accompanying drawings, in Which- Figure l is a central vertical section, and Fig. 2 an elevation of the entire apparatus and a bottle set in it.

A, Fig. l, is a jacket surrounding the bottle B of milk C which is to be warmed.

D is a lining in the socket or carrier M, on Whichthe bottle B rests.

E is a shield or diffusing-plate placed be tween the socket M and iiame F of the burner or lamp G.

H Il are a frame carrying and holding in their respective places the sockets M, shield E, and lamp Gr.

I Ir are feet on the frame I-I Il'. These feet rest on a plate J, which has an air-space K under it.

The jacket A is made of a shape and length to surround the bottle B about as high as it is filled with milk and to reach down below the bottom of the bottle and below the shield E. This jacket may be of sheet metal, but is most economical if made of a non-heat-conducting material or lined with such material on the inside. The size of the jacket A is such as to leave a space L L' all around the bottle B.

Patent No. 584,162, dated June 8, 1897'.

Serial No. 541,324. (No model.)

Vthe heat of the llame F strikes and is distributed allaround through the space or open ings N N', past the socket M into the space L Ll all around the bottle B. This action of the shield E, together with the non-heat-conducting liningD in the socket M, keeps the bottom of the bottle B from getting much warmer than the body of it, and not only prevents cracking of the bottle but also obviates handling the bottle at the top only, as would have to be done if the bottom got too hot to handle.

The frame H H' may be varied in form or design or made partof a jacket A by extending the jacket down to the plate J and providing holes for air and for putting in the lamp or burner G.

The burner G shown is a small metal cup made to hold only enough alcohol to warm the bottle of milk (l to the desired temperature when all the alcohol is burned. When the bottle C is not full of milk, or in case a smaller bottleful is to be warmed, the cup is filled with alcohol in proportion only and may be marked or graded to shovT quantity of alcohol required for different quantities of milk.

The base J, with the air-space K, may be varied in shape or even omitted and the feet I I' ext-ended instead, but the plate and air space are a safeguard to keep the heat from damaging the furniture on which the warmer may set and to catch any liquid which may be spilled.

To use the warmer, set the bottle B into the jacket VA onto the carrier D M. Take out the cup G and pour in as much alcohol as a test has shown to be required to Warm the milk. Light the alcohol and set the cup into its place at once. The ilame will be small at iirst and gradually grow larger as the cup gets warmer. For this reason, together with the action of the shield E and lined carrier D M, the bot- IOO tle will not crack, but become warmed gradually, and it will Warm quickly because the jacket A conducts all the heat around and along the entire length of the bottle and prevents the heat from escapingin any other direction. Y

If a number of bottles are to be War med successively, a lamp With an adjustable burner may be used in place of the cup G and the desired temperature attained by timing, or if a steam-heater, stove-top, or other source of heat is at hand the base J, feet I I', burner Gr, and frame II Il Will not be required. If gas is at hand, a holder fitting the gas-burner maybe provided in place of the frame II H and feet I I, and the gas-flame used instead of the burner G.

Having fully described my invention and pointed out the several useful features thereof, I claim as new and desire to secure byLetters Patentl. In a Warming apparatus, the combination of a socket or carrier, a diffusing-plate under this carrier, an air-space surrounding these tWo parts, a jacket or fine inclosing this air-space, arms 0r holders extending inward from the jacket and holding, the diffusingplate and socket, a lamp-holder and base attached to the lower end of the jacket, and a lamp or heater fitted thereto, substantially as described.

2. In a Warming apparatus, the combination of an open-cup burner, a holder for this burner attached to a jacket or fine provided with internal arms or brackets carrying a diffusing plate or shield above the burner and a carrier or socket above this plate, substantially as described.
